Video: Xylem & Phloem

Front

What is translocation in the context of phloem?

Back

The transport of sugars and amino acids to where they are needed.

Front

What are the primary products transported by phloem?

Back

Sugars, mostly sucrose, and amino acids.

Front

What is the primary method of nutrient acquisition in unicellular organisms?

Back

Through diffusion across their cell membrane.

Front

How is the xylem vessel adapted to its function?

Back

It has a hollow lumen strengthened by lignin.

Front

Which direction does water flow through the xylem?

Back

From roots to leaves.

Front

What is the main function of xylem in plants?

Back

To transport water and dissolved minerals from the roots to the rest of the plant.

Front

What is the main function of phloem in plants?

Back

To transport organic nutrients, particularly sugars, from the leaves to other parts of the plant.

Front

What are the two main types of vascular tissue in plants?

Back

Xylem and phloem.

Front

What is lignin and its role in xylem?

Back

Lignin is a complex organic polymer that strengthens the cell walls of xylem vessels, allowing them to withstand the pressure of water transport.

Front

What is the process of photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.
